Coral reef fisheries depend on reef fish biomass to support ecosystem functioning and sustainable fisheries. Here, we evaluated coral reefs across 4,000 km of the Indonesian archipelago to reveal a large gradient of biomass, from <100 kg/ha to >17,000 kg/ha. Trophic pyramids characterized by planktivore dominance emerged at high biomass, suggesting the importance of pelagic pathways for reef productivity. Total biomass and the biomass of most trophic groups were higher within gear restricted and no‐take management, but the greatest biomass was found on unmanaged remote reefs. Within marine protected areas (MPAs), 41.6% and 43.6% of gear restricted and no‐take zones, respectively, met a global biomass target of 500 kg/ha, compared with 71.8% of remote sites. To improve conservation outcomes for Indonesia's biodiverse and economically important coral reef fisheries, our results suggest to: (1) strengthen management within Indonesia's existing MPAs and (2) precautionarily manage remote reefs with high biomass.

捕鱼的限制和偏远为印度尼西亚的珊瑚礁渔业带来了保护成果

珊瑚礁渔业依靠珊瑚礁生物量来支持生态系统的功能和可持续渔业。在这里，我们评估了印度尼西亚群岛4,000公里范围内的珊瑚礁，发现生物质的梯度很大，从<100千克/公顷到> 17,000千克/公顷。以浮游生物优势为特征的营养金字塔出现在高生物量上，表明浮游途径对珊瑚礁生产力的重要性。在档位限制和禁捕管理下，总营养量和大多数营养组的生物量较高，但在不受管理的偏远珊瑚礁上发现的生物量最大。在海洋保护区（MPA）中，分别有41.6％和43.6％的渔具限制区和禁渔区达到了500 kg / ha的全球生物量目标，而偏远地区为71.8％。改善印尼的保护成果
